4.3 C6000 Legacy Intrinsics

All legacy intrinsics defined in c6x_migration.h are available for use in C7000 Host Emulation. Their interface is the same as it is with the C7000 compiler.

Section 8 discusses requirements regarding legacy data types and assumptions about their SIMD usage. As a result of those limitations, all legacy data types must be treated as container types. That is, all initialization and interaction with legacy data types must be through intrinsics. Section 8 also contains examples of how to program with legacy data types and intrinsics when using C7000 Host Emulation. The C6000-to-C7000 Migration User's Guide (SPRUIG5) and the c6x_migration.h header file should be used as references any time C6000 code is used within a C7000 program.
